Oil Temperature (Engine) Sensor

Corvette is equipped with an oil temperature sensor. If sensor indicates oil temperature is high when it should be low, or low when it should be high, a trouble Code 52 (low) or 62 (high) will set in ECM memory; however, sensor will not cause driveability problems. Sensor information is sent from ECM to be used by Central Control Module (CCM) to determine oil life expectancy. If an oil temperature sensor code is set in memory, CCM has been calculating oil life from inaccurate ECM input. Oil and filter must be changed, code must be cleared and oil life monitor must be reset.

To reset oil life monitor, turn ignition on. Depress ENG MET button on trip monitor and release. Within 5 seconds, depress and release ENG MET button again. Within 5 seconds, depress and hold the RANGE button on trip monitor. The CHANGE OIL light should flash.

Hold the RANGE button depressed until the CHANGE OIL light stops flashing and goes out. When the light goes out, the engine oil life monitor is reset. This should take about 10 seconds. If the light does not reset, turn the ignition off and repeat the procedure.
